What is membrane separation and how does it work?
Membrane separation is a physical process that uses a semi-permeable membrane to selectively separate components in a gas or liquid mixture based on differences in molecular size, charge, or chemical affinity. A pressure difference across the membrane acts as the driving force, allowing certain molecules to pass through (permeate) while retaining others (retentate). This technology is widely used in industries like petrochemical, natural gas processing, and water treatment for applications ranging from gas purification to solvent recovery.
